Systems and methods for secured data transfer via inter-chip hopping buses

Abstract

Systems and methods described herein provide a method for secured data transfer via inter-chip hopping buses. The method includes configuring a non-volatile storage element located within a first electronic component to be pre-programmed with a first unique identifier associated with a first electronic component. The method further includes configuring a first scramble pattern generator located within the first electronic component for generating a first scramble pattern based on a first counter value at runtime of the first electronic component. The method further includes configuring a first XOR gate located within the first electronic component to receive the first scramble pattern from the first scramble pattern generator and data from a transceiver buffer for generating output data to be transmitted out of the first electronic component.

AI Technical Summary

Benefits of technology

The patent describes a system and method for secure data transfer between electronic components using inter-chip hopping buses. The system includes a non-volatile storage element with a unique identifier and a scramble pattern generator that generates a scramble pattern based on a counter value at runtime. The system also includes an XOR gate to receive the scramble pattern and data from a transceiver buffer to generate output data for transmission. The method also includes configuring a receiver component to receive the output data and control packets to enforce security checks. The system and method provide a way to securely transfer data between electronic components and prevent unauthorized access.

Problems solved by technology

If probing circuitry is added to the communication chip, the decrypted data may be intercepted by the probing circuitry.

Thus, the originally encrypted multimedia data may be exposed to a third party by the probing circuitry and the data security of the circuit is damaged.
